Im, Jaewan published the artcileStructural characteristics and thermal properties of regenerated cellulose, hemicellulose and lignin after being dissolved in ionic liquids, SDS of cas: 79917-90-1, the publication is Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) (2022), 365-375, database is CAplus.
This study investigated the use of ionic liquids such as 1-butyl-3-methylimidazolium chloride, 4-butyl-4-Me morpholinium chloride, 1-butyl-1-methylpiperidinium chloride, and 1,3-dimethylimidazolium methylphosphite to dissolve cellulose, hemicellulose, and lignin biomass, as alternatives to highly toxic organic solvents. The biomass treated with the ionic liquids is characterized by SEM, X-ray diffraction, thermogravimetric anal., and Fourier-transform IR spectroscopy. The X-ray diffraction results revealed that most of the biomass treated with ionic liquids had low crystallinity after treatment with the ionic liquids Thermogravimetric anal. confirmed that the pyrolysis temperature of the biomass treated with the ionic liquid decreased. However, it was found that the pyrolysis temperature of the biomass was increased again after the ionic liquid was washed with an antisolvent. This result was interpreted using Fourier-transform IR spectroscopy to show that the O-H hydrogen bonding of cellulose was restored. The exptl. results from this study can help provide a better understanding of the biomass regeneration mechanism of ionic liquids and increase the applicability of biomass in various fields.
